Dealing with Long-Term RV Antifreeze

If you have left RV antifreeze in your pipes for more than 10 months, don't panic. While it is generally recommended to flush your system at the start of the season, pink RV antifreeze is non-toxic and designed for winterization.

The biggest issue isn't the antifreeze itself, but the potential for it to degrade or pick up debris if the system wasn't fully sanitized beforehand. Perform a thorough flush with fresh water until the pink hue is completely gone, then follow up with a food-grade system sanitizer to ensure your potable water lines are safe for the season.

Water Heater Storage Best Practices

Leaving water in your heater tank during long-term storage is a recipe for corrosion and bacterial growth. If your rig is sitting idle, always ensure the water heater is drained completely.

Use a tank rinser to remove sediment that builds up at the bottom of the heater. If you are preparing to head out to a spot like [Hidden Valley RV Park](/park/hidden-valley-rv-park), make sure to bypass your water heater before flushing the lines to prevent filling the tank with antifreeze or cleaning solutions.

Thriving During Holiday Weekend Occupancy

Holiday weekends bring high occupancy levels to popular destinations. When parks are at capacity, utilities like water pressure and electrical stability can fluctuate significantly.

To protect your rig, always use a high-quality water pressure regulator and a surge protector. Arriving early or booking in advance is essential when planning a stay at high-demand locations like [Sunset Ridge Campground](/park/sunset-ridge-campground). Being prepared for crowds means double-checking your battery levels and grey water capacity before you depart, ensuring your system is ready for a busy weekend where external support might be stretched thin.
